Yeung Gor nearly died in ROCH because of the Passion Flower Poison that he had been exposed to. It seemed that nothing, not even Gwok Jing's 9 Yum Jen Ging energy or the Indian Healer Monk's medical skill, could help him. His only hope was to obtain the antidote that Kau Cheen Chek alone possessed (or the Deun Chang Grass that ultimately proved to be Yeung Gor's salvation). Yeung Gor's adoptive father, West Poison Au Yeung Fung, was the greatest master of poison the world had ever seen, but he was dead by the time that Yeung Gor became exposed to the Passion Flower Poison. With his expert knowledge of poisons, could Au Yeung Fung have devised a cure for the Passion Flower Poison?
